Help Boot looping! How to stop?

[Zombiegal]

OK so I have a Samsung Infuse 4g from Att and its not rooted and its running gingerbread. Last night i was reading the news shut the screen off with lock button and noticed a few minuets later when i returned to the room to finish reading the news i was reading..... it was in boot loop. Ok so i saw where the power button is possibly sticking.... they recommend smacking the phone on your hand power button at the bottom and it should pop it out... i did this .... it did not work. Right now as soon as i make a connection with the battery to the phone it shows Samsung and loops over and over.

So what do I do? I cant afford a new phone right now

Is the power button still stuck down?

Since, if i grasp what you are trying to explain, is as soon as you put the battery in, the device turns on and starts boot looping?
